TSMC sole supplier of 10nm SoCs for the iPhone 7?

9to5Mac picked up news that TSMC could be the only supplier of 10nm A10 SoCs for the Apple iPhone 7. TSMC is expected to enter mass production in June and Apple is exected to announce its new smartphone sometime in September. The A9 SoC of the iPhone 6S series was made by TSMC and Samsung, but users noticed that phones with chips made by TSMC ran noticeably cooler and offered a slightly better battery life:

Following the launch of the iPhone 6s and 6s Plus last year, users started noticing differences in the performance of models using the TSMC-made A9 chip and the Samsung-made A9 chip. Benchmark tests and videos showed that an iPhone 6s with the TSMC chip ran cooler and offered better battery life than an iPhone with a Samsung chip did. Apple even came out and commented on the discrepancy, saying that “even taking into account variable component differences” battery life between iPhone 6s models could vary within 2-3 percent of each other.
